Description

[0002] With the continuous expansion of the new energy vehicle market, the demand for new energy vehicle power batteries is also expanding, and correspondingly, the die cutting equipment also needs higher productivity. In the manufacturing process of power batteries, the material belts that need to be cut mainly include positive electrode sheets, negative electrode sheets and separator membranes. In use, the raw materials of these material belts need to be cut into the required width, and the cut material belts are respectively wound to facilitate storage and transportation. Usually, one wide material belt can be cut into multiple narrow material belts.

[0003] In the winding process, a winding device is used to wind the cut material belt. When a winding shaft winds a certain length of the belt, the material belt needs to be pulled to another winding shaft, and the material belt on the winding shaft that has been wound is cut off. In order to improve the roll changing efficiency, a roll changing device is usually used to automatically complete the pulling and cutting of the material belt. When pulling the material belt, the cutter of the roll changing device needs to avoid the material belt; after pulling is completed, the cutter needs to cut the material belt.

[0004] In related technologies, the efficiency of the cutter in switching between the avoiding state and the cutting state is low, resulting in low roll changing efficiency. UTILITY MODEL CONTENT

[0068] Reference Figures 1 to 4 According to the first aspect embodiment of the cutting module 100 of the present application, the cutting module 100 includes a cylinder 110, a cutter 120 and a first driving assembly 130. The cylinder 110 includes a side wall 111, which encloses a receiving hole 112. The side wall 111 is provided with a slit 113, and the axial direction of the cylinder 110 is the first direction (refer to Figure 1 , for example, the first direction is the left-right direction), and the length direction of the slit 113 is arranged along the first direction. The slit 113 is in communication with the receiving hole 112, and the slit 113 penetrates the first outer surface 114 of the side wall 111. The first outer surface 114 is used to abut with the material belt 500 (refer to Figure 9 )。

[0069] The position of the cutter 120 completely accommodated in at least one of the receiving hole 112 and the slit 113 is the first position (refer to Figure 3 , Figure 3 The cutter 120 in the first position) in the first position. The position of the cutter 120 protruding from the slit 113 and exposed from the first outer surface 114 is the second position (refer to Figure 4 , Figure 4 The cutter 120 in the first position) in the first position);

[0070] The first driving assembly 130 is configured to drive the cutter 120 to move from the first position to the second position, and to drive the cutter 120 to move from the second position to the first position. The first driving assembly 130 is also configured to drive the cutter 120 in the first direction when the cutter 120 is in the second position, so as to cut the tape 500 attached to the first outer surface 114.

[0071] The cutting module 100 according to the embodiments of the present application has at least the following beneficial effects: when the cutter 120 is in the first position, the cutter 120 is completely accommodated in at least one of the accommodating hole 112 and the gap 113, and the cutter 120 does not protrude from the first outer surface 114, so that the cutter 120 can avoid the tape 500; when the cutter 120 is in the second position, the cutter 120 protrudes from the first outer surface 114, and the cutter 120 is in a position capable of cutting the tape 500 (when cutting, the cutter 120 in the second position needs to be driven to move in the first direction), and the first driving assembly 130 is configured to quickly switch the cutter 120 between the first position and the second position, so as to effectively improve the efficiency of the cutter 120 in switching between the avoiding state and the cutting state.

[0072] It should be noted that the first outer surface 114 generally refers to the outer circumferential surface of the barrel 110. The cutter 120 protrudes from the first outer surface 114, which means that the cutter 120 protrudes from the gap 113, and a part of the cutter 120 is located in the space outside the barrel 110.

[0073] Referring to Figure 1 , Figure 2 and Figure 5 , in some embodiments of the present application, the width direction of the gap 113 is the second direction (see Figure 1 , for example, the second direction is the up-down direction), and the first driving assembly 130 includes a guide seat 140, a connecting seat 150, and a driving member 160. The guide seat 140 is located in the accommodating hole 112, and the guide seat 140 is connected to the barrel 110. The guide seat 140 is provided with a first guide groove 141, and the first guide groove 141 includes a first groove 142 and a second groove 143, and the first groove 142 is in communication with the second groove 143. The extension direction of the first groove 142 and the second direction form an angle less than 90 degrees, and the extension direction of the second groove 143 and the first direction form an angle less than 90 degrees.

[0074] The connecting seat 150 includes a first seat body 151, a second seat body 153, and a first connecting member 154. The cutter 120 and the first connecting member 154 are both mounted on the first seat body 151, and the first connecting member 154 is inserted into the first guide groove 141. The first seat body 151 is slidably connected to the second seat body 153, and the sliding direction of the first seat body 151 relative to the second seat body 153 forms an angle less than 90 degrees with the second direction. The driving member 160 is configured to drive the second seat body 153 to move in the first direction.

[0075] Thus, under the action of the driving member 160, the second seat body 153 can drive the first seat body 151 to move along the first direction, and the first seat body 151, while moving along the first direction, will also move along the second direction due to the action of the first slot 142 and the first connecting member 154, thereby driving the cutter 120 to move along the second direction, and the cutter 120 will move from the first position to the second position.

[0076] When the first connecting member 154 moves from the first slot 142 to the second slot 143, the cutter 120 at the second position only moves along the first direction, thereby completing the cutting of the material belt 500.

[0077] The first driving assembly 130 has a relatively simple and reliable structure, and can realize the switching of the cutter 120 between the first position and the second position and the movement of the cutter 120 at the second position along the first direction at a low cost.

[0078] It should be noted that the angle between the extension direction of the first slot 142 and the second direction is less than 90 degrees, so that the first connecting member 154 has a component displacement in the second direction when sliding in the first slot 142. The first connecting member 154 is installed on the first seat body 151, so the first seat body 151 and the cutter 120 have a component displacement in the second direction, and the cutter 120 can move along the second direction, i.e., the cutter 120 can retract into the gap 113 or extend out of the gap 113, and the cutter 120 can be switched back and forth between the first position and the second position.

[0079] It should be noted that since the first direction and the second direction can be perpendicular (for example, the first slot 142 is a cuboid-shaped slot), the angle between the extension direction of the first slot 142 and the second direction cannot be 90 degrees. When the angle between the extension direction of the first slot 142 and the second direction is 90 degrees, the first connecting member 154 will not be able to move along the second direction.

[0080] The first seat body 151 and the second seat body 153 are in sliding connection, and the angle between the sliding direction of the first seat body 151 relative to the second seat body 153 and the second direction is less than 90 degrees, which can realize the movement decoupling between the first seat body 151 and the guide seat 140, and also allows the second seat body 153 to have a force on the first seat body 151 along the second direction (i.e., the second seat body 153 can push the first seat body 151 to move along the second direction).

[0081] If the angle between the sliding direction of the first seat 151 relative to the second seat 153 and the second direction is 90 degrees, the second seat 153 no longer has a force on the first seat 151 along the second direction, and the second seat 153 cannot push the first seat 151 to move along the second direction. If the first seat 151 is fixedly connected to the second seat 153, the first connecting piece 154 will be stuck in the first slot 142, that is, the first seat 151 will be stuck by the guide seat 140, and the driving member 160 cannot drive the second seat 153 to move along the first direction.

[0082] Specifically, the first connecting piece 154 includes a first rolling bearing 158, and the first rolling bearing 158 is fixed to the first seat 151 by a bolt, and the first rolling bearing 158 can roll along the inner surface of the first guide slot 141. In another embodiment, the first connecting piece 154 can also include a first pin.

[0083] Specifically, the cutting module 100 usually further includes two end covers 170, and the two end covers 170 are respectively fixed to the two ends of the barrel 110 by fasteners (such as bolts), and the two ends of the guide seat 140 are respectively fixed to the two end covers 170 by fasteners (such as bolts).

[0084] Specifically, the angle between the extension direction of the first slot 142 and the second direction can be 0 degrees, 30 degrees, 45 degrees, 60 degrees, or other angles. Preferably, the angle between the extension direction of the first slot 142 and the second direction is 45 degrees.

[0085] Specifically, the angle between the sliding direction of the first seat 151 relative to the second seat 153 and the second direction can be 0 degrees, 30 degrees, 45 degrees, 60 degrees, or other angles. Preferably, the angle between the sliding direction of the first seat 151 relative to the second seat 153 and the second direction is 0 degrees.

[0086] Specifically, the angle between the extension direction of the second slot 143 and the first direction can be 0 degrees, 30 degrees, 45 degrees, 60 degrees, or other angles. Preferably, the angle between the extension direction of the second slot 143 and the first direction is 0 degrees.

[0087] Referring to Figure 2 and Figure 6 In some embodiments of the present application, the first driving assembly 130 further includes an elastic member 155, and the elastic member 155 is used to drive the first seat 151 to move relative to the second seat 153, so that the cutter 120 located at the second position has a movement trend of continuing to extend from the slit 113.

[0088] By arranging the elastic member 155, the cutter 120 can always maintain an outwardly extending state, the position of the cutter 120 is relatively stable, and the cutter 120 can stably cut the material belt 500.

[0089] It should be noted that, due to the action of the elastic member 155, when the cutter 120 in the second position wants to extend from the slot 113 to a certain position (for example, the second position), the first connecting member 154 will abut against the inner surface (referring to Figure 2 , for example, the upper surface) of the second groove 143, so as to stabilize the position of the cutter 120 and prevent it from extending from the slot 113.

[0090] Referring to Figure 2 and Figure 6 , in the improved scheme of the above embodiment, the elastic member 155 includes a compression spring 157, both ends of the compression spring 157 abut against the first seat body 151 and the second seat body 153 respectively, and when the cutter 120 is in the second position, the compression spring 157 is in a compressed state.

[0091] The abutment of both ends of the compression spring 157 against the first seat body 151 and the second seat body 153 respectively can make the cutter 120 in the second position have a movement trend of continuing to extend from the slot 113, and the structure is simple, the function is stable, and it is beneficial to reduce the production cost of the cutting module 100.

[0092] Specifically, referring to Figure 8 , in order to realize the installation of the compression spring 157 and avoid the compression spring 157 from being separated out from between the first seat body 151 and the second seat body 153, the first driving assembly 130 further includes a bolt 156. The second seat body 153 is provided with a stepped hole 191, and the stepped hole 191 includes a large hole 192 and a small hole 193. The first seat body 151 is provided with a threaded hole 194. The lower end of the compression spring 157 is arranged in the large hole 192, and the lower end of the compression spring 157 abuts against the stepped surface 195 of the stepped hole 191. The upper end of the compression spring 157 abuts against the second seat body 153. The bolt 156 passes through the stepped hole 191 and the compression spring 157, and is threadedly connected with the threaded hole 194, so as to realize the installation of the compression spring 157.

[0093] When the compression spring 157 works, it is limited by the bolt 156 and cannot move excessively in the horizontal direction, so that the compression spring 157 cannot be separated out from between the first seat body 151 and the second seat body 153.

[0094] Specifically, referring to Figure 6 and Figure 8 , in order to balance the force acting on the second seat body 153, two compression springs 157 and two bolts 156 are arranged, and the two compression springs 157 and the two bolts 156 are matched respectively, so as to simultaneously apply forces to both ends of the second seat body 153, and the second seat body 153 is balanced and is not easy to be skewed.

[0095] In another embodiment, the elastic member 155 can also be a bellows, a rubber tube, a silica gel tube, a tension spring or other parts. The bellows, the rubber tube and the silica gel tube are installed in the same way as the compression spring 157. For the tension spring, only one end of the tension spring is hung on the first seat body 151, and the other end of the tension spring is hung on the head of the bolt 156, so that the cutter 120 in the second position has a tendency to continue to extend out of the slot 113 by pulling the bolt 156 upward.

[0096] Referring to Figure 5 In some embodiments of the present application, the angle between the extension direction of the second slot 143 and the first direction is zero.

[0097] The angle between the extension direction of the second slot 143 and the first direction is zero, so that when the first connecting member 154 moves along the second slot 143, the cutter 120 will not have a movement along the second direction, and the movement of the cutter 120 is more stable.

[0098] Referring to Figure 2 In some embodiments of the present application, the driving member 160 includes a rodless cylinder 161, and the rodless cylinder 161 includes a sliding table 162 and a cylinder body 163. The cylinder body 163 is connected with the barrel 110. The sliding table 162 is connected with the second seat body 153, and the sliding table 162 can move along the first direction relative to the cylinder body 163.

[0099] By using the rodless cylinder 161, the driving of the second seat body 153 can be realized with simpler structure and cost.

[0100] Referring to Figure 2 In another embodiment, the driving member 160 can also be one of a linear motor, a motor-driven crank slider mechanism, a motor-driven gear rack mechanism, a motor-driven screw nut mechanism and a motor-driven chain sprocket mechanism.

[0101] In the improved scheme of the above embodiment, in order to reduce the friction between the cylinder body 163 and the barrel 110, the connecting seat 150 further includes a second connecting member 152. The guide seat 140 is provided with a second guide slot 144, and the angle between the extension direction of the second guide slot 144 and the first direction is less than 90 degrees. The second connecting member 152 is inserted into the second guide slot 144, and the second connecting member 152 can slide along the second guide slot 144.

[0102] Therefore, when the compression spring 157 transmits pressure to the second seat body 153, the second seat body 153 can transmit the pressure to the guide seat 140 through the second connecting member 152, thereby reducing the friction between the cylinder body 163 and the barrel 110.

[0103] Specifically, the second connecting member 152 comprises a second rolling bearing 159, the second rolling bearing 159 is mounted on the second seat body 153 by a bolt, and the second rolling bearing 159 can roll along the inner surface of the second guide groove 144. In another embodiment, the second connecting member 152 can also comprise a second pin.

[0104] With reference to Figure 2 In some embodiments of the present application, the cutting module 100 further comprises a position sensor 180, the position sensor 180 is mounted on the cylinder body 110, and the position sensor 180 is used to detect two end point positions of the stroke of the cutter 120 in the first direction.

[0105] By detecting the two end point positions of the cutter 120 by the position sensor 180, it is beneficial to judge whether the cutter 120 has completed the cutting of the material belt 500, thereby facilitating to improve the degree of automation control of the cutter 120.

[0106] With reference to Figure 2 For example, the two end point positions of the stroke in the first direction are the left end point position and the right end point position of the cutter 120.

[0107] Specifically, with reference to Figure 2 The position sensor 180 comprises a first photoelectric sensor 181, and the first photoelectric sensor 181 is provided with two, and the two first photoelectric sensors 181 are respectively mounted on the two ends of the guide seat 140.
